MCP3913A1T-E/MV

Overview

The MCP3913A1T-E/MV is a six-channel energy metering analog front end (AFE) manufactured by Microchip Technology. It integrates six 24-bit delta-sigma analog-to-digital converters (ADCs) designed for high-accuracy signal acquisition in three-phase smart meters. The device supports a serial SPI interface and operates on a 3V supply voltage. It features programmable data rates up to 125 ksps, enabling flexible power consumption scaling or advanced harmonic analysis. The component includes CRC-16 checksum and register-map lock capabilities to enhance system robustness.

Feature Summary

• Integrates six 24-bit delta-sigma ADCs for simultaneous multi-channel signal acquisition
• Includes CRC-16 checksum and register-map lock mechanisms for data integrity
• Supports programmable sampling rates up to 125 ksps for adaptable performance

Applications

• Three-phase smart electricity meters
• High-accuracy energy monitoring systems
• Multi-sensor utility metering applications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus tube variants. Confirm AEC-Q100 automotive qualification status if required for the target application. Ensure the SPI interface compatibility matches the host microcontroller specifications. Check for any recent product change notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when six independent measurement channels are required within a single package. Consider the 24-bit resolution and high SINAD performance for precision metering tasks. Evaluate the 3V operating voltage against system power constraints. Compare with the eight-channel MCP3914 variant if additional sensor inputs are needed.
